THOMAS E. MCNEILL, OF NEW YORK, N. Y.

GAS-RADIATO R.

SPECIFICATION forming part of Letters Patent No. 744,787, dated November 24, 1903.

' Application filed December 31, 1902. Serial No. 137,339. (Nomodel-l To a/Z whom it mayooncern:

Be it known that I, THOMAS E. MONEILL, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and useful Improvement in Gas-Radiators, of which the following is a full, clear, and exact description.

My invention relates to improvements in heat-radiators adapted to the use of gaseous or liquid fuel. V V

In this invention I seek to produce a simple, compact, and efficient structure having arelatively large heating and radiating surface and making provision for carrying off the gaseous products. of combustion to the end that they will not be discharged into a room or apartment. The burner or burners are located quite close to the floor, so as to secure the circulation of warm currents of air close to the floor. In, the service of the radiator an inducedcirculation of cold air from the room and through the structure is obtained, and the air to be warmed is brought into contact with the surfaces of the radiator in such a way as to prevent overheating" thereof. The air supplied to the burner is drawn from the room and discharged, with the products of combustion, to secure ventilation of the The-hot products of combustion 1 to the end that the escape thereof may be retarded and the latent heat may be absorbed to better advantage by the radiating-surfaces of the structure.

Further objects and advantages of thein vention will appear in the course of the subjoined description, and the novelty will be defined by the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation taken 1on gitudinally through a gas-radiator embodying one form of my invention, the plane of the section being indicated by the irregular line 1 1 of Fig. 2. Fig. 2 is a sectional plan view the radiator.

on line 2 2 of Fig. 1. Fig. 3 is a vertical cross-section on line 3 3 of Fig. 1. Figs. 4, 5, and 6 are views of another embodiment of my invention, Fig. 4 being a" vertical longitudinal section 011 the line 4 4: of Fig. 5, Fig. 5 being a sectional plan view on a plane above the base, and Fig. 6 being a vertical crosssection on the line 6 6 of Fig. 4.

I will first proceed-to describe that form of .my invention which is shown by Figs. 1 to 3,

inclusive, of the drawings, inwhich I employ a hollow or chambered base 5, having depending feet 6. This base is provided with a top plate 7, while the under side of the base is open, as at 8, thus providing for the free admission of air to the bottom part of the radiator. The base is furthermore provided with longitudinal compartments 9 l0 and with a transverse exit-flue 11. The compartments 9 10 are indicated by dotted lines in Fig. 2 as arranged on opposite sides of the longitudinal axis of the radiator, and these compartments do not communicate with each other, although they are connected with the exit-flue 11 at the middle of the radiator.

My improved radiator may consist of one or more longitudinal sections, but I prefer to employ the two longitudinal sections shown more particularly by Figs. 2 and 3. Each longitudinal section consists of a pair of complemental corrugated members A B and an intermediate fiat member or plate 0. The members A B are disposed in pairs and on opposite sides of the flat plate C, and these parts A B O extend practically the full length'of The members A B may be corrugated in any suitable way, substantially as shown by Fig. 2, and said members are assembled in matching relation, so that. the corrugations thereof will form vertical cells or compartments. The flat plate 0 is interposed between the'adjacent portions of the corrugated members A B, and this plate serves to divide the cells or compartments in a way to form circulating-fiues through the section of the radiator.

The plate 0 is coextensive with the corrugated members AB, and these parts maybe united at their end portions or at points intermediate of their length, as desired. The corrugated member A forms on one side of the plate 0 a series of ascendingheat-flues D, which communicate directly with one chamber of the base by a series of large openings 15, the latter being formed in the top plate 7 of the base. The corrugated member 13 forms on opposite sides of the plate a series of descending flues E, and these fines E have communication with the ascending heat-ii ues D by means of openings m, which are provided in the upper edge portion of the interposed plate 0. (See Fig. 3.) These descending flues E have communication with the chambers 9 or 10 of the base through a series of openings 16, which are formed in the top plate 7; but one feature of my invention consists in making these openings of diiferent sizes, the larger openings being provided at the lower ends of the fiues,which lie at the end portions of the radiator, the said openings decreasing in size from the end flues toward the exit-fine 11, thus regulating the escape of the products of combustion from the descending lines into the base and hence to the exit-flue. I have stated that the radiator has two longitudinal sections, and in this embodiment of the invention the sections are so disposed that the corrugated members B thereof are arranged in opposing or facing relation and in such a way as to provide a series of ascending airflues F G. (See Fig. 2.) The air-fluesF are between the approximate parallel portions of the corrugated members B of the two sections, whereas the fines G are bounded by the inclined or curved portions of the corrugations in the members B. Obviously the members A B may be corrugated in a different way from the specific disclosure embodied in Fig. 2, and in this event the form and arrangement of the air-lines between the longitudinal sections will vary. The air-fines F between said longitudinal sections have communication with the chambered base by openings 12 in the top plate 7 thereof, whereas the lines G communicate by openings 14c with said base. The corrugations of the members A form between themselves two series of air-spaces I J on the outside of the radiator, and these air-spaces communicate with the chamber of the base by openings 13,which are formed in the top plate 7. The sections formed by the corrugated and flat members are superposed on the base, and they are surmounted by a cast-1nctal top plate ll, the same having openings 10, which communicate with the ascending air-flues F G. The longitudinal sections, the metallic top plate, and the east-metal base are united in any suitable way, and, if desired, the space between the opposing corrugated members 13 of the longitudinal sections may be closed at the ends of the radiator by the plates or walls h. (See Fig. 2.)

The improved radiator herein described is equipped with burners adapted to consume gaseous or liquid fuel, the said burners being indicated at 17 18. The burners extend 1011- gitudinally of the radiator, and they lie immediately below the openings 15 and the series of ascending heat-fines D. The burners in the type shown are adapted to be supplied with gaseous fuel and with air in a way to serve as Bunsen burners; but it will be understood that I reserve the right to employ any kind of burnersuch, for example, as a perforated pipe adapted to be supplied with gas and with external atmosphere which is drawn from the room or apartment in which the radiator is located. If desired, however, I may employ a burner of suitable construction and adapted to consume liquid fuel, and it is therefore to be understood that my invention contemplates the employment of any kind of a burner except a burner of that type which is adapted to consume solid or carbonaceous fuel. \Vhen the burners 17 18 are in use, the gaseous products of combustion pass through the openings 15 into the ascending heat-iiuesl) and through the openingsm of the members 0, so as to travel in a downward direction through the descending heatflues E, from whence they pass through the openings 16 into the chambers 9 10 and make their exit through the flue 11.. The operation of the burners draws air through the base 5 to the flame emanating from the orifices of said burners, thus inducing a circulation of air along the floor of the room, which air commingles with the gaseous products of combustion and passes through the radiator and from the exit-flue 11, therebyventilating the room or apartment. The circulation of the heated products of combustion through the lines 0 I) heats the several walls of the members forming the longitudinal sections, and from these walls the heat is radiated. The radiation of heat from the members 13 induces a circulation of currents of air through the airflues F G, while the radiation of heat from the members A induces a circulation through the lines I .I, whereby a large volume of air is caused to circulate through the radiator without comminglin g with the gaseous products of combustion, and the heat is also radiated from certain walls of the structure directly into the room or apartment.

In the type of radiator shown by Figs. 4:, 5, and (3 the base 5 is chambered and provided with the exitflue 11; but instead of using the series of members which form the pl urality of separate heat lines and airfines and which require the employment of at least two burners I have devised a construction contemplating the use of a single burner 20 and which secures the circulation of the products of combustion upwardly and downwardly throughthe radiator. ()11 the base 5 is erected a shell 0, having its walls corrugated in any desired way, such as indicated at 0 in Fig. 5. \Vithin the shell 0 is arranged a shorter internal shell 1, which is carried by the base 5, but which does not extend to the cap-plate 12, that is supported on the outside shell O. This internal shell forms a 1011 gitudinal vertical ascending heat flue Q, which opens through the base 5" for the free inlet of air and the products of combustion that emanate from the burner 20, the latter being situated directly below the flue Q and extending longitudinally of the radiator, as shown by Figs. 4 and 5. Between the shells O P are the descending heat -flues Q, and

these dues or chambers communicate with the exit-flue 11 atthe middle of the radiator through a series of openings 21, formed in' the top plate 7 of the base 5. The openings of each flue decrease in size from the middle of the radiator toward the ends thereof to control the escape of the heat. In one of the flues or chambers Q is arranged a damper 23, having perforations of different size toator as being rectangular in shape, it is .to be understood that the shape as well as the size, proportions, and minor details of construction are immaterial features of this invention. such changes and alterations as fall within the scope of the annexed claims.

Having thus described my invention, I claim as new and desire to secure byLetters Patent- 1. A radiator consisting of corrugated and plate members assembled into cooperative relation to produce ascending and descending flues and also to form cold-air flu es within the limits of the radiator.

2. A radiator consisting of corrugated and plate members assembled to produce sections of the structure, said members forming ascending and descending fiues in the sections and cold-air flues between the sections.

I therefore reserve the right to make 3. A radiator consisting of corrugated and plate members assembled to produce ascending and descending heat-fines and intervening flues open to the atmosphere, and a burner arranged to supply heat to the ascending fiues.

4:. A radiator consisting of a base, an exitflue for the products of combustion, hollow and plate members assembled one within the,

other and forming ascending and descending fiues within the structure, said descending flue or flues communicating with the exit-flue by. a series of graduated openings which increase in area from the middle of the structure toward the ends thereof, and a burner in communication with the ascending flue or flues.

5. A radiator consisting of a base, hollow and plate members assembled one within the other and forming ascending and descending flues, the hollow member or members being corrugated, a'burner in communication with THOMAS E. MONEILL.
